The Schedule referred to in these Letters Patent and making part of the s ame 'To whom e't may concerne p lBe it known that L'Fnnnnnicn A. Become, of Jackson, in the county of Jackson and State of Michigan, have invented'a new and useful Improvement in Grain-Separators; and I do declare that the following is a true and accurate description thereof, reference being had to theaccompanying drawingan'd to the letters of `reference marked thereon, and being a part of this specification, in which` Figure lis a side elevationgof my separator, with a part of the vcasing broken. away to show the shoe;

Figure -2 is a longitudinalvertical section .of the same. i

The nature of'this invention relates to an improve-r inentin the construction'ofgrain-sepai'ators, and consists in the general arrangement of its various parts, as

more fully, hereinafter set forth. In.thefdrawingf` j y. A represents the frainefwork of my separator.

' In the upper bea-m'vof .the frame is ljournaled -the `fan-shaft, rotated by the geai" B through the'pinion j Disa craiikedjshait, journaled in the frame ol' the inachinenndcr the iancase, andl is rotated' bythe gear i .B through its-pinion, D'L

The screen is laterally vib'rated by a link, l), conwhose other. arm .is connected, by a rod, d, with a Under the upper half of the screen-flame is a case or receptacle, L', provided with a spout,l e, which discharges its contents at the side of the machine. .lhe screeii-fraine,'over the receptacle, is provided with a screen,` M, of suoli mesh that the small impurities, which are too heavy to be blown away by the blast, will drop through and be discharged by the spout e, while the wheat will pass along down onto a screen,

N, which covers the lower section ofthe frame. This screen should be oi' such mesh-that the largest and pliii'npest berries, which are desirable to save for seed, cannot pass through, but will he dischargedat the front end of' the inachineinto a boX placed' there for the purpose, while the rest ofthe grain passing through the screen Nris received in a grain-drawer, 0, below.

Itwill be noticed that the grain, falling in a thin stream on the rst screeini'eceives the'full force of ther blast, which at once rids it of the lighter impurities, while thesticks andother substances of a size "too great to pass through that screen are discharged by it. ,"lhis leaves no impurities in the grain except they be small ,and heavy, and which are discharged with the grain from the rear end of the shoeonto the `upper end of the screen M, which eliminates theiiiv y screen N. v L I In cleaning and separating seeds and grains other from `the grain, which `is subsequently graded by the than'wheat, the screens of pi'opeimesh should `be einspout c', the screens kM aud-N, and grain-drawer O, .4 Iwhen arranged in the manner and tor the purpose herein shown and described,
